NLC and whole-cell currents recorded from bundleless OHCs and IHCs. A, NLC measured from two representative OHCs 4 and 11 d after their hair bundles were ablated. The cells were held at 0 mV and two-sinusoidal voltage protocols were used to probe voltage-dependent NLC. NLC was plotted in black thin lines while the Boltzmann function used to fit the response was in heavy black lines. B, Whole-cell currents measured from two representative IHCs in cultures 4 and 11 d after their hair bundles were removed. The cells were held at −70 mV. The membrane potential varied from −120 to 80 mV in 20 mV steps.
